Or maybe GDS32.DLL(or FBCLIENT.DLL). We had that problem very recently
with one of our customers, and I was able to reproduce it myself(with
SS or CS). Basically, what happens is if the UDF references GDS32.DLL,
then GDS32.DLL needs to be somewhere in the path, the same can be said
of FBCLIENT.DLL. And, the same folder as the UDF doesn't always work.
